CYBERWALL™ INSTALLATION, OPERATION AND MAINTENANCE MANUAL
STARTUP/COMMISSIONING
Operation
For new installations, ensure the unit is ready to operate by completing the startup checklist Appendix A.
NOTE
A Warranty Registration and Start-Up Checklist is provided with the unit data package. It should be
completed during start-up and sent to STULZ. This checklist should be used as a guideline for items that
need to be confirmed during start-up.
Start-up must be performed by a qualified refrigeration mechanic or air conditioning technician.
Start-Up Instructions
1. Ensure that the control circuit breakers, fan power switch (motor starter protectors) and additional built in
optional equipment power switches are turned on.
2. Close all cabinet doors and replace all equipment removed prior to performing start-up checks.
3. Verify correct power before energizing the unit.
4. Apply power to the CyberWall™ system at the main power disconnect switch in the main electric box.
5. Turn on the unit using the system controller and set the desired values (set points) for room temperature.
6. Ensure that all fans are rotating correctly and freely without any unusual noise.
WARNING
This unit employs high voltage equipment with rotating components. Exercise extreme care to avoid
accidents. Always keep hands, clothing and tools clear of the fan blades when power is On.
7. Test cooling operation by setting the temperature setpoint below actual room temperature. The chilled
water valve should open and the fan speed should increase. The discharge air should feel cooler than the
return air.
Controller Programming
The system controller is factory programmed. Most applications require no adjustment beyond setting the
current date and time and temperature set points.
